SX2—4—10型箱式电阻炉是现代工业部门应用广泛的小型钢件热处理设备,主要用于冶金和机械行业热处理方面。在长期的使用过程中,其炉丝会老化变脆而断裂,如果在工厂中能自行绕制的话,不仅能提高劳动效率,而且能降低经济成本。在长期的生产实践中,我们摸索出一套行之有效的自制 SX2-4-10-type box-type resistance furnace is a widely used in the modern industrial sector small steel heat treatment equipment, mainly used in metallurgical and mechanical industries heat treatment. In the long-term use of the process, the furnace will become brittle and breakage of the aging of the furnace, if the factory can be self-winding, not only can improve labor efficiency, but also reduce economic costs. In long-term production practice, we explore a set of effective self-control
